MIPS/BFD: Correct microMIPS cross-mode BAL to JALX relaxation

Fix a bug in commit a6ebf6169a1b ("MIPS: Convert cross-mode BAL to
JALX") and in BFD linker relaxation correct the microMIPS interpretation
of the branch offset, which is supposed to be shifted by 1 bit, rather
than 2 as in the regular MIPS case.
